Comparison of urgent and early endoscopy for acute non-variceal upper gastrointestinal bleeding in high-risk patients.

OBJECTIVE: Data regarding early (within 24h) and urgent endoscopy (within 12h) in non-variceal upper gastrointestinal bleeding (NV-UGIB) revealed conflicting results. This study aimed to investigate the impact of endoscopy timing on the outcomes of high-risk patients with NV-UGIB. PATIENTS AND METHODS: From February 2020 to February 2021, consecutive high-risk (Glasgow-Blatchford score ≥12) adults admitted to the emergency department with NV-UGIB were analyzed retrospectively. The primary composite outcome was 30-day mortality from any cause, inpatient rebleeding, need for endoscopic re-intervention, need for surgery or angiographic embolization. RESULTS: 240 patients were enrolled: 152 (63%) patients underwent urgent endoscopy (<12h) and 88 (37%) patients underwent early endoscopy (12-24h). One or more components of the composite outcome were observed in 53 (22.1%) patients: 30 (12.5%) had 30-day mortality, rebleeding occurred in 27 (11.3%), 7 (2.9%) underwent endoscopic re-intervention, and 5 (2.1%) required surgery or angiographic embolization. The composite outcome was similar between the groups. Multivariate analysis showed only hemodynamic instability on admission (OR: 3.05, p=0.006), and the previous history of cancer (OR: 2.42, p=0.029) were significant in predicting composite outcome. In terms of secondary outcomes, the endoscopic intervention was higher in the urgent endoscopy group (p=0.006), whereas the number of transfused erythrocyte suspensions and the length of hospital stay was higher in the early endoscopy group (p=0.002 and p=0.040, respectively). CONCLUSIONS: Urgent endoscopy leads to a significant reduction in the length of hospitalization and the number of transfused erythrocyte suspensions in NV-UGIB, which can contribute to patient satisfaction, reduce healthcare expenditure, and improve hospital bed availability. The composite outcome and its sub-outcomes were the same among both groups.

One- or two-operator techniques for oesophago-gastro-duodenoscopy in unsedated patients: A comparative prospective randomized study.

BACKGROUND: The standard oesophago-gastro-duodenoscopy procedure is performed with a single endoscopist (SE). Nurse-assisted (NA) oesophago-gastro-duodenoscopies have not yet been studied. We aimed to evaluate the efficacy of an NA endoscopy compared to an SE endoscopy. METHODS: A prospective, single-center, randomized trial, in which 500 adult patients were divided into two groups. In the first group, patients underwent an endoscopy with an SE. In the second group, the endoscopy was performed with an NA. The ease of the procedure (scores 1-4; 1 difficult, 2 satisfactory, 3 easy, 4 veryeasy), evaluation of patient satisfaction (scores 1-4; 1 uncomfortable, 2 satisfactory, 3 comfortable, 4 verycomfortable), total time of the procedure and vocal cord observation were determined as quality indicators. RESULTS: Mean patient satisfaction scores in groups 1 and 2 were 2.98±0.79 and 3.11±0.78, respectively (p=0.043), with uncomfortable ratings in 5.2% vs 4%, satisfactory in 16.8% vs 13.2%, comfortable in 53.2% vs 50.4%, and very comfortable in 24.8% vs 32.4% of patients in groups 1 and 2, respectively. Retching rates during the procedure were 54.4% and 45.2% (p=0.040) in groups 1 and 2, respectively. No differences were seen in vocal cord observation (54.4% vs 56.0%), total procedure time (2.35±1.56 vs 2.41±1.48min) and easy score (3.26±0.603 vs 3.25±0.64) in groups 1 and 2 for the procedures. Very easy, easy, satisfactory, and difficult ratings were given by 33.6% vs 34.8%, 60.4% vs 56.4%, 4.8% vs 7.6% and 1.2% vs 1.2% of groups 1 and 2, respectively. CONCLUSIONS: Compared with the conventional method, the assisted endoscopic technique provides more comfort and less gag reflex without increasing the processing time or difficulty of performing the procedure.

Role of the gastroenterologist in the management of the obese patient. / Papel del digestólogo en el manejo del paciente obeso.

Obesity is a highly prevalent disease worldwide, and one in which gastroenterologists can play an important role. Some digestive diseases are more common in obese patients, and preoperative evaluation may be required in some cases. Additionally, bariatric surgery can lead to digestive complications in the short and long term that require intervention, and endoscopic treatment can be an important factor in weight loss. The aim of this review is to highlight the role of the gastroenterologist in the management of obese patients who are either scheduled for or have undergone surgical or endoscopic treatment for obesity.

Implementation and evaluation of early gastroscopy for patients with dyspepsia and warning signs in Primary Care. / Implantación y evaluación de una prestación de gastroscopia precoz para pacientes con dispepsia y datos de alarma en Atención Primaria.

INTRODUCTION: Dyspepsia is a common disorder in both Primary (PC) and Specialised Care (SC). Gastroscopy is recommended at the start of the study if there are warning signs, although it is not always available in PC. OBJECTIVES AND METHODS: We developed a pilot project establishing an early gastroscopy programme for patients with dyspepsia and warning signs in PC, subsequently extending it to the entire healthcare area. The aim was to evaluate the requirements, impact and opinion of this service at the PC level. Demographic, symptomatic and endoscopic variables on the patients referred to SC from the pilot centre were recorded. A satisfaction survey was conducted among the PC physicians. RESULTS: The one-year pilot study and the first year of implementation of the programme were evaluated. A total of 355 patients were included (median age 56.4 years; IQR 45.5-64.3); 61.2% (56.1-66.3%) were women. The waiting time for examination was 1.5 weeks (IQR 1.5-2.5). Gastroscopy was correctly indicated in 82.7% (78.4-86.3%) of patients. The median number of requests per month was 1.1 per 10,000 adults (range 0.8-1.6). Monthly referrals to SC clinics from the pilot centre fell by 11 subjects (95% CI 5.9-16) with respect to the previous median of 58 (IQR 48-64.5). Almost all those polled (98.4%) considered the programme useful in routine practice. CONCLUSIONS: The availability of an early gastroscopy programme in PC for patients with dyspepsia and warning signs reduced the number of referrals to SC.

Reducción de la infección por Helicobacter pylori en pacientes derivados a endoscopia digestiva alta en Santiago de Chile entre 2010-2020 / Reduction in Helicobacter pylori infection among patients referred for upper gastrointestinal endoscopy in Santiago, Chile, between 2010-2020

RESUMEN Latinoamérica presenta una alta prevalencia de infección por Helicobacter pylori (Hp). Entre 1996-2003 la prevalencia en Santiago de Chile fue del 70%; estudios recientes presentan una disminución en esta infección. Actualizar la frecuencia de Hp es fundamental debido a su impacto en la salud asociado. Objetivo: Nuestro objetivo fue describir la tendencia de la infección por Hp en pacientes que asisten a endoscopía digestiva alta (EDA) ambulatoria en una población chilena. Materiales y métodos: Se realizó un estudio observacional retrospectivo de pacientes mayores de 18 años que asistieron a una primera EDA con test rápido de ureasa entre 2010-2020. La tendencia en el tiempo fue descrita mediante análisis de series de tiempo. Se construyó un modelo Poisson para estimar el riesgo de infección, ajustado por edad y sexo. Resultados: Se incluyeron 11 355 pacientes [66,9% mujeres; edad media 52 años; Hp 41,6%]. El sexo masculino presentó una mayor frecuencia de infección por Hp [RR 1,13; (IC95%:1,08-1,18)]. La frecuencia de Hp disminuyó significativamente desde 45,1% en 2010 hasta 29% en 2020, con 36% menor probabilidad de presentar infección por Hp en 2020 con respecto al 2010 [RR 0,64; (IC95%:0,55-0,74)]. Se proyectó un descenso progresivo en la tendencia de infección por Hp hasta valores cercanos al 25% para el año 2025. Conclusión: Se observó una reducción significativa en la infección por Hp entre los años 2010-2020. Esta disminución pudiese ser explicada mediante la incorporación de políticas públicas de salud en la última década asociadas a cambios sociosanitarios.

ABSTRACT Latin America presents a high prevalence of Helicobacter pylori (Hp) infection. Between 1996-2003, the prevalence in Santiago, Chile, was 70%; recent studies indicate a decrease in this infection. Updating the frequency of Hp is crucial due to its associated health impact. Objective: Our objective was to describe the trend in Hp infection in patients undergoing ambulatory esophagogastroduodenoscopy (EGD) in a Chilean population. Materials and methods: A retrospective observational study was conducted on patients over 18 years old who attended a first EGD with a rapid urease test between 2010-2020. Time trends were described through time series analysis. A Poisson model was constructed to estimate the risk of infection, adjusted for age and gender. Results: 11,355 patients were included [66.9% females; mean age 52 years; Hp 41.6%]. Male gender presented a higher frequency of Hp infection [RR 1.13; (95% CI: 1.08-1.18)]. Hp frequency infection decreased significantly from 45.1% in 2010 to 29% in 2020, with a 36% lower probability of Hp infection in 2020 compared to 2010 [RR 0.64; (95% CI: 0.55-0.74)]. A progressive decline in Hp infection trend was projected, reaching values close to 25% by year 2025. Conclusion: A significant reduction in Hp infection was observed between 2010-2020. This decrease could be explained by the implementation of public health policies in the last decade associated with socio-sanitary changes.

Infección por Helicobacter pylori y factores asociados en adultos de la sierra norte del Perú / Helicobacter pylori infection and associated factors in adults from the northern highlands of Peru

INTRODUCCIÓN: Helicobacter pylori afecta a más de 50% de la población mundial, siendo más prevalente en poblaciones de nivel socioeconómico bajo; esta bacteria constituye la principal causa de cáncer gástrico a nivel global. OBJETIVO: Determinar la frecuencia y los factores asociados a la infección por H. pylori en personas adultas que viven en el centro histórico de la ciudad de Cajamarca, en el norte del Perú. MATERIAL Y MÉTODO: Estudio descriptivo que incluyó 124 personas encuestadas mediante un cuestionario y evaluadas mediante endoscopía y cultivo de biopsia gástrica. Una biopsia por persona fue sometida a prueba de ureasa y los cultivos se confirmaron por reacción de polimerasa en cadena (RPC). RESULTADOS: La frecuencia de infección fue de 60,5 % (IC 95% 51,3 - 69,2). El análisis univariado demostró asociación significativa entre la infección y la edad (p = 0,002), y entre la infección y el antecedente de patología gástrica (p = 0,015). El análisis multivariado reveló dos factores asociados: edad (OR = 0,94; IC95% 0,90-0,97) y antecedente de infección por H. pylori (OR = 0,23; IC95% 0,08 - 0,67). CONCLUSIONES: Existe alta frecuencia de infección por H. pylori en esta población; la edad y el antecedente de infección constituyen factores asociados que deben evaluarse con mayor profundidad.

BACKGROUND: Helicobacter pylori affects more than 50% of the world's population, being more prevalent in populations of low socioeconomic status. H. pylori is the main cause of gastric cancer globally. AIM: To establish the frequency and factors associated with H. pylori infection in adults living in the historic center of Cajamarca City, in northern Peru. METHODS: This was a descriptive study that included 124 individuals surveyed through a questionnaire and evaluated through endoscopy and gastric biopsy culture. One biopsy per person underwent the urease test, and the cultures were confirmed by PCR. RESULTS: The frequency of infection was 60.5% (95% CI 51.3 - 69.2). In the univariate analysis, there was a significant association between the infection and age (p = 0.002), and between the infection and a history of gastric pathology (p = 0.015). The multivariate analysis revealed two associated factors: age (OR = 0.94; 95% CI 0.90 - 0.97), and history of H. pylori infection (OR = 0.23; 95% CI 0.08 - 0.67). CONCLUSIONS: There is a high frequency of H. pylori infection in this population, and the age and history of H. pylori infection are factors that should be further evaluated.

Gastrointestinal bleeding in patients with COVID-19: an integrative review / Sangramento gastrointestinal em pacientes com COVID-19: uma revisão integrativa

ABSTRACT Introduction: In 2020, the world suffered a major impact from the COVID-19 pandemic, especially due to the high transmissibility of the virus. It is a disease that predominates with respiratory manifestations, but there is involvement of the gastrointestinal tract, causing symptoms ranging from mild to more severe. Highlighting gastrointestinal bleeding, it is a symptom resulting from the involvement of the SARS-CoV-2 virus described by several reports and case series. Methods: through an integrative literature review, of a qualitative nature, works that corresponded to the eligibility criteria were selected, totaling 16 articles included in this review. Results: of the patients who manifested gastrointestinal symptoms associated with the disease, common comorbidities and clinical manifestations were identified, in addition to therapies used to treat the infection, which were predisposing factors for the development of gastrointestinal bleeding. Conclusion: The presence of gastrointestinal bleeding in patients with COVID-19 is established in the literature, since the pathophysiological mechanisms of the disease directly affect the GIT. Early recognition of symptoms and suspicion of gastrointestinal involvement allows better management of patients and complications.

RESUMO Introdução: em 2020 o mundo sofreu um grande impacto com a pandemia pela doença COVID-19, em especial pela alta transmissibilidade do vírus. É uma doença que predomina com manifestações respiratórias, porém existe um acometimento do trato gastrointestinal, causando desde sintomas leves a mais graves. Destacando o sangramento gastrointestinal, é um sintoma decorrente do acometimento do vírus SARS-CoV-2 descrito por diversos relatos e séries de casos. Métodos: por meio de uma revisão integrativa da literatura, de caráter qualitativo, foram selecionados trabalhos que correspondessem aos critérios de elegibilidade, totalizando 16 artigos incluídos nesta revisão. Resultados: dos pacientes que manifestaram sintomas gastrointestinais associados a doença, foram identificadas comorbidades e manifestações clínicas em comum, além de terapias utilizadas como tratamento da infecção, que foram fatores predisponentes para o desenvolvimento de sangramentos gastrointestinais. Conclusão: a presença de sangramento gastrointestinal em pacientes com COVID-19 é um dado firmado na literatura, uma vez que os mecanismos fisiopatológicos da doença afetam diretamente o TGI. O reconhecimento precoce dos sintomas e a suspeita do acometimento gastrointestinal permite um melhor manejo dos pacientes e das complicações.

Resumo Objetivo Para pacientes idosos, a endoscopia gastrointestinal indolor pode facilmente induzir eventos adversos. Nosso objetivo foi avaliar os efeitos de intervenções de enfermagem de alta qualidade nos resultados e na taxa de complicações de pacientes idosos submetidos à endoscopia gastrointestinal indolor. Métodos Foram selecionados 124 pacientes que receberam endoscopia gastrointestinal indolor no período de janeiro a dezembro de 2022, 62 dos quais internados entre janeiro e junho de 2022 foram incluídos em um grupo de enfermagem convencional e receberam intervenção de enfermagem básica tradicional, e os outros 62 internados entre julho e dezembro 2022 foram atribuídos a um grupo de enfermagem de alta qualidade e receberam intervenções de enfermagem de alta qualidade. Os resultados da intervenção foram comparados. Resultados As pontuações da Escala de Autoavaliação de Ansiedade e da Escala de Autoavaliação de Depressão do grupo de enfermagem de alta qualidade foram inferiores às do grupo de enfermagem convencional (P<0,05). A pressão arterial sistólica, a pressão arterial diastólica e a frequência cardíaca durante e após o diagnóstico e tratamento diminuíram no grupo de enfermagem de alta qualidade em comparação com os do grupo de enfermagem convencional (P <0,05). O grupo de enfermagem de alta qualidade teve uma taxa de complicação mais baixa e uma taxa de satisfação de enfermagem mais alta do que o grupo de enfermagem convencional (P<0,05). Conclusão A intervenção de enfermagem de alta qualidade não só estabiliza o estado psicológico dos pacientes idosos submetidos à endoscopia gastrointestinal indolor, mas também é benéfica para manter a pressão arterial e a frequência cardíaca estáveis.

Abstract Objective For elderly patients, painless gastrointestinal endoscopy can easily induce adverse events. We aimed to evaluate the effects of high-quality nursing interventions on the outcomes and complication rate of elderly patients undergoing painless gastrointestinal endoscopy. Methods A total of 124 patients who received painless gastrointestinal endoscopy from January to December 2022 were selected, 62 of whom admitted between January and June 2022 were included into a conventional nursing group and given traditional basic nursing intervention, and the other 62 admitted between July and December 2022 were assigned into a high-quality nursing group and given high-quality nursing intervention. The intervention outcomes were compared. Results The Self-rating Anxiety Scale and Self-rating Depression Scale scores of the high-quality nursing group were lower than those of the conventional nursing group (P<0.05). The systolic blood pressure, diastolic blood pressure, and heart rate during and after diagnosis and treatment decreased in the high-quality nursing group compared with those in the conventional nursing group (P<0.05). The high-quality nursing group had a lower complication rate and a higher nursing satisfaction rate than those of the conventional nursing group (P<0.05). Conclusion High-quality nursing intervention not only stabilizes the psychological state of elderly patients undergoing painless gastrointestinal endoscopy, but also is beneficial to maintaining stable blood pressure and heart rate.

Early and severe onset of esophageal dysfunction after laparoscopic sleeve gastrectomy: a case report and review of literature / Inicio temprano y severo de disfunción esofágica después de manga gástrica laparoscópica: reporte de caso y revisión de la literatura

ABSTRACT After bariatric surgery one of the most common complications is dysphagia. The etiology of this disease has not been fully elucidated but it is known that it may be due to structural changes due to surgery. This case describes a 65-year-old female with early and severe onset of dysphagia following laparoscopic sleeve gastrectomy. The patient's final diagnosis was postobesity surgery esophageal dysfunction and laparoscopic proximal gastrectomy with esophagojejunal Roux-en-Y anastomosis was performed. Physicians should be aware of this condition in order to offer early diagnosis and treatment.

RESUMEN Después de una cirugía bariátrica una de las complicaciones más comunes es la disfagia. La etiología de esta enfermedad no ha sido completamente dilucidada, pero se sabe que puede deberse a cambios estructurales debidos a la cirugía. En este reporte se describe el caso de una mujer de 65 años con disfagia severa de aparición temprana después de una en manga gástrica laparoscópica. El diagnóstico final del paciente fue de una disfunción esofágica posterior a una cirugía de obesidad y se planteó como manejo una gastrectomía proximal laparoscópica con anastomosis esofagoyeyunal en Y de Roux. Hay que tener en cuenta las complicaciones a corto y largo plazo que se pueden presentar luego de cirugías de obesidad para poder realizar un diagnóstico temprano y poder ofrecer un tratamiento adecuado.

Acurácia do escore de referência endoscópico para esofagite eosinofílica em crianças / Accuracy of the eosinophilic esophagitis endoscopic reference score in children

ABSTRACT Background: To assess the efficacy of applying the endoscopic reference score for EoE (EREFS) in children with symptoms of esophageal dysfunction naïve to proton pump inhibitor (PPI) therapy. Methods: An observational cross-sectional study was conducted by reviewing reports and photographs of upper gastrointestinal endoscopies (UGE) and esophageal biopsies of patients with symptoms of esophageal dysfunction. Patients who were treated with PPI or had other conditions that may cause esophageal eosinophilia were excluded. Results: Of the 2,036 patients evaluated, endoscopic findings of EoE were identified in 248 (12.2%) and more than one abnormality was observed in 167 (8.2%). Among all patients, 154 (7.6%) presented esophageal eosinophilia (≥15 eosinophils per high power field) (P<0.01). In this group, 30 patients (19.5%) had normal endoscopy. In patients with EoE, edema (74% vs 6.5%, P<0.01) and furrows (66.2% vs 2.4%, P<0.01) were more prevalent than in the control group. Association of edema and furrows was more frequent in patients with EoE than in the control group (29.2% vs 1.6%, P<0.01, OR=24.7, CI=15.0-40.5). The presence of more than one endoscopic finding had sensitivity of 80.5%, specificity of 93.4%, positive predictive value (PPV) of 50%, negative predictive value (NPV) of 98.3%, and accuracy of 92.4%. Conclusion: In conclusion, this study showed that endoscopic features suggestive of EoE had high specificity and NPV for diagnosing EoE in children naïve to PPI therapy. These findings highlight the importance of the EREFS in contributing to early identification of inflammatory and fibrostenosing characteristics of EoE, making it possible to identify and to avoid progression of the disease.

RESUMO Contexto: Avaliar a eficácia da aplicação do escore de referência endoscópico para EoE (EREFS) em crianças com sintomas de disfunção esofágica sem tratamento prévio com inibidores da bomba de prótons (IBP). Métodos: Foi realizado um estudo transversal observacional por meio de revisão de laudos e fotos de endoscopia digestiva alta (EDA) e biópsias de esôfago de pacientes com sintomas de disfunção esofágica. Pacientes tratados com IBP ou com outras condições que podem causar eosinofilia esofágica foram excluídos. Resultados: Dos 2.036 pacientes avaliados, os achados endoscópicos de EoE foram identificados em 248 (12,2%) e mais de uma anormalidade foi observada em 167 (8,2%). Entre todos os pacientes, 154 (7,6%) apresentaram eosinofilia esofágica (≥15 eosinófilos por campo de grande aumento) (P<0,01). Nesse grupo, 30 pacientes (19,5%) apresentaram endoscopia normal. Em pacientes com EoE, edema (74% vs 6,5%, P<0,01) e linhas verticais (66,2% vs 2,4%, P<0,01) foram mais prevalentes quando comparados ao grupo controle. A associação de edema e linhas verticais foi mais frequente em pacientes com EoE do que no grupo controle (29,2% vs 1,6%, P<0,01, OR=24,7, IC=15,0-40,5). A presença de mais de um achado endoscópico teve sensibilidade de 80,5%, especificidade de 93,4%, valor preditivo positivo de 50%, valor preditivo negativo de 98,3% e acurácia de 92,4%. Conclusão: Em conclusão, esse estudo mostrou que as características endoscópicas sugestivas de EoE apresentam especificidade e VPN elevados para o diagnóstico da enfermidade em crianças sem tratamento prévio com IBP. Estes achados reforçam a importância do EREFS em contribuir para a identificação precoce de características inflamatórias e fibroestenosantes, possibilitando identificar e evitar a progressão da doença.

Visión general de las várices gástricas y su tratamiento / Overview of gastric varices and their treatment

Las várices gástricas (VG) son un complejo de colaterales vasculares entre la circulación portal y sistémica, condición que se desarrolla como resultado de la presión elevada en el sistema venoso portal. Se encuentran en el 20 % de los pacientes con cirrosis, y son menos frecuentes que las várices esofágicas. Según la clasificación de Sarin, las VG se dividen en cuatro tipos según su ubicación en el estómago y su relación con las várices esofágicas (GOV1, GOV2, IGV1 e IGV2). Entender su hemodinámica con respecto a las rutas de drenaje de las VG es importante para guiar su tratamiento.

Gastric varices (GV) are a complex of vascular collaterals between portal and systemic circulation, a condition that develops as a result of elevated pressure in the portal venous system. They are found in 20% of patients with cirrhosis, and are less common than esophageal varices. According to the Sarin classification, GV are divided into four types based on their location in the stomach and their relationship with esophageal varices (GOV1, GOV2, IGV1, and IGV2). Understanding their hemodynamics with respect to GV drainage routes is important to guide their treatment.

Resección laparoscópica de quiste de duplicación gástrica asistida por endoscopia / Laparoscopic resection of gastric duplication cyst assisted by endoscopy

Introducción. Las duplicaciones gástricas son entidades congénitas poco frecuentes que se diagnostican principalmente en las etapas tempranas de la vida, y rara vez en pacientes adultos. El objetivo de este artículo fue presentar el caso de un adulto con esta patología, tratado exitosamente mediante cirugía. Caso clínico. Mujer de 26 años de edad con epigastralgia crónica refractaria a manejo médico, a quien durante endoscopia digestiva superior se le identificó una lesión quística sugestiva de tumor estromal gastrointestinal, confirmada por ultrasonido endoscópico. Resultados. Se realizó una resección quirúrgica laparoscópica asistida por endoscopia, con buena evolución postoperatoria. El estudio anatomo-patológico informó la presencia de un quiste de duplicación gástrica. Conclusiones. A pesar de las ayudas diagnósticas disponibles en la actualidad, esta patología representa un reto diagnóstico importante que, en muchas ocasiones solo puede ser confirmado mediante el estudio anatomo-patológico. En paciente asintomático, continúa la controversia entre observarlo o llevarlo a cirugía, por el riesgo de malignidad. Actualmente, el manejo de las duplicaciones gástricas en adultos se considera eminentemente quirúrgico. Las resecciones laparoscópicas y el uso de endoscopia intraoperatoria permiten garantizar la resección completa de la lesión, preservando la mayor cantidad de tejido sano adyacente y previniendo estenosis o deformidades gástricas que afecten su adecuado funcionamiento.

Introduction. Gastric duplications are rare congenital entities that are diagnosed primarily in early life, and rarely in adult patients. The objective of this article was to present the case of an adult with this pathology, successfully treated by surgery. Clinical case. A 26-year-old woman with chronic epigastralgia refractory to medical management, who during upper digestive endoscopy was identified with a cystic lesion suggestive of gastro-intestinal stromal tumor, confirmed by endoscopic ultrasound. Results. A laparoscopic surgical resection assisted by endoscopy was performed, with good postoperative evolution. The anatomopathological study reported the presence of a gastric duplication cyst. Conclusions. Despite the diagnostic adjuncts currently available, this pathology represents an important diagnostic challenge that, in many cases, can only be confirmed through pathology. In asymptomatic patients, the controversy continues between observing them or taking them to surgery due to the risk of malignancy. Currently, the management of gastric duplications in adults is considered eminently surgical. Laparoscopic resections and the use of intraoperative endoscopy ensure complete resection of the lesion, preserving the greatest amount of adjacent healthy tissue and preventing gastric stenosis or deformities that affect its proper functioning.

Manejo de perforaciones, fugas y fístulas del tracto gastrointestinal con clip sobre el endoscopio. Experiencia de un centro oncológico Latinoamericano / Management of perforations, leaks and fistulas of the gastrointestinal tract with over the scope clip. Experience at a Latin American cancer center

Introducción. Las fístulas derivadas de enfermedades neoplásicas del tracto digestivo, así como las fugas posteriores a procedimientos quirúrgicos, no son infrecuentes y ocasionan una morbilidad importante cuando se manejan de forma quirúrgica. También durante los procedimientos endoscópicos se pueden presentar perforaciones y, si se logra un manejo no operatorio, se alcanza una adecuada recuperación. El objetivo de este estudio fue describir las características clínicas y los resultados de los pacientes con perforaciones, fístulas y fugas del tracto gastrointestinal, manejadas endoscópicamente con clip sobre el endoscopio. Métodos. Estudio descriptivo, retrospectivo, de pacientes con perforación, fuga o fístula postoperatoria, llevados a endoscopía digestiva con colocación de clip sobre el endoscopio, en el Instituto Nacional de Cancerología en Bogotá, D.C., Colombia, entre enero de 2016 y abril de 2020. Resultados. Se incluyeron 21 pacientes, 52,4 % de ellos mujeres. La mediana de edad fue de 66 años y del diámetro del defecto fue de 9 mm. En el 95 % se logró éxito técnico. Hubo éxito clínico temprano en el 85,7 % de los casos. El 76,1 % de los pacientes permanecieron sin síntomas a los 3 meses de seguimiento. Conclusiones. El manejo de perforaciones, fugas y fístulas con clip sobre el endoscopio parece ser factible y seguro. En la mayoría de estos pacientes se logró la liberación del clip y la identificación endoscópica del cierre inmediatamente después del procedimiento; sin embargo, en el caso de las fístulas, no se alcanzó el éxito clínico tardío en todos los casos

Introduction. Fistula of the digestive tract derived from neoplastic diseases as well as leaks following surgical procedures are not uncommon and usually cause significant morbidity when are managed surgically. Diagnostic and therapeutic endoscopic procedures may present perforations during their performance; if they are managed non-operatively, an adequate recovery is obtained. The purpose of this study was to describe the clinical characteristics and the short- and long-term outcomes of patients with perforations, fistulas and leaks of the gastrointestinal tract managed endoscopically with over the scope clip (OTSC). Methods. Descriptive, retrospective study of patients brought to digestive endoscopy with OTSC placement with diagnosis of postoperative perforation, leak or fistula at the National Cancer Institute in Bogota, Colombia, between January 2016 and April 2020. Results. Twenty-one patients were taken for OTSC application for the management of perforations, leaks and fistulas of the gastrointestinal tract, 52.4% of them were women. The median age was 66 years. The median diameter of the defect was 9 mm. Technical success was achieved in 95%. Early clinical success was described in 85.7% of the cases; 76.1% of patients remained symptom-free at 3-month follow-up. Conclusions. Management of perforations, leaks and fistulas with OTSC appears to be feasible and safe. In most of these patients, clip release and endoscopic identification of closure was achieved immediately after management; however, in the case of fistulas, late clinical success was not achieved in all cases

Drainage of Pancreatic Pseudocysts Using Lumen-apposing Metal Stents (LAMS): Experience in Two Referral Centers in Colombia

Introduction: Endoscopic ultrasound (EUS)-guided drainage and luminal-apposing metal stents (LAMS) are the options for managing symptomatic pancreatic pseudocysts. Aim: To evaluate the effectiveness and safety of LAMS for EUS-guided drainage of symptomatic pancreatic pseudocysts in two referral centers in Colombia. Materials and methods: A multicenter prospective cohort study between June 2019 and December 2021 included 13 patients diagnosed with symptomatic pancreatic pseudocysts who underwent EUS-guided drainage with LAMS. Technical success, clinical success, and successful stent removal were evaluated as outcomes. Safety outcomes included stent-related adverse events and general adverse events. Follow-up was carried out for eight weeks, collecting data on stent removal. Results: The average age was 53.4 years; 8/13 were men. The mean size of the pseudocyst was 9.56 ± 2.3 cm. Technical success was 100%, and clinical success was 92.3%. The stents were removed on average after 8 ± 2 weeks. The mean procedural time from puncture to stent deployment was 3.2 ± 2.4 minutes. In the imaging check-up, the collections had adequate drainage in all cases. There was a low frequency of complications; bleeding was documented in one case requiring surgery. Conclusions: LAMS is safe and effective in managing symptomatic pancreatic pseudocysts, reducing hospital stay and cost overruns. Clinical symptomatology prevails in the surgery decision.

El tiempo medio del procedimiento desde la punción hasta el despliegue del stent fue 3,2 ± 2,4 minutos. En el control imagenológico hubo un adecuado drenaje de las colecciones en todos los casos. Hubo baja frecuencia de complicaciones, se documentó sangrado en 1 caso con requerimiento quirúrgico. Conclusiones: el uso de LAMS es seguro y efectivo en el manejo de pseudoquistes pancreáticos sintomáticos, disminuye la estancia hospitalaria y sobrecostos. La sintomatología clínica prima en la decisión de intervención.

Textiloma intrabdominal incidental

Introducción: Los textilomas son cuerpos extraños originados a partir del material quirúrgico textil, olvidado durante una intervención quirúrgica. Son poco frecuentes. Su forma de presentación clínica puede ser aguda o crónica y se manifiestan meses o años después de la operación quirúrgica original. Objetivos: Presentar un caso poco frecuente de textiloma intrabdominal, sus manifestaciones clínicas, diagnóstico y tratamiento. Caso clínico: Paciente masculino de 39 años de edad, con antecedentes de haber sido operado hace 14 años de úlcera duodenal sangrante, asintomático hasta la fecha en que se estudió por síntomas digestivos. Como único elemento positivo al examen físico se constató dolor a la palpación profunda en epigastrio. Durante la endoscopía se diagnosticó una lesión subepitelial gástrica. En la tomografía con doble contraste de abdomen se corroboró una lesión de aspecto tumoral en la curvatura mayor del estómago, dependiente de su pared. Se realizó ultrasonido endoscópico mediante el cual se diagnosticó un tumor mesenquimal del mesenterio, sin poder descartar la posibilidad de un tumor del estroma gastrointestinal gástrico. Se realizó exéresis del tumor. El estudio anatomopatológico informó textiloma. Conclusiones: Los textilomas son accidentes quirúrgicos con consecuencias perjudiciales para la vida del paciente si no se procede rápidamente. Son el resultado de la iatrogenia durante una intervención quirúrgica y lo más importante es su prevención.

Introduction: Textilomas are foreign bodies originating from the textile surgical material, forgotten during a surgical intervention. They are rare. Its clinical presentation can be acute or chronic, manifesting months or years after the original surgical operation. Objectives: To present a rare case of intra-abdominal textiloma, its clinical manifestations, diagnosis and treatment. Clinical case: A 39-year-old male patient with a history of been operated on 14 years ago for a bleeding duodenal ulcer; asymptomatic until the date he was studied for digestive symptoms. The only positive element in the physical examination was pain on deep palpation of epigastrium. During endoscopy, a gastric subepithelial lesion was diagnosed. The double-contrast abdominal tomography confirmed a tumor-like lesion at the greater curvature of the stomach, depending on its wall. An endoscopic ultrasound was performed, through which a mesenchymal tumor of the mesentery was diagnosed, without being able to rule out the possibility of a gastric gastrointestinal stromal tumor. Excision of the tumor was performed. The anatomopathological study reported a textiloma. Conclusions: Textilomas are surgical accidents with detrimental consequences for the patient's life if not proceeded quickly. They are the result of iatrogenesis during a surgical intervention and the most important thing is their prevention.

Gastric twist after sleeve gastrectomy: a proposal for endoscopic classification / Torção gástrica após gastrectomia vertical: uma proposta de classificação endoscópica

ABSTRACT - BACKGROUND: The twisting of the gastric tube is one of the main causes of persistent reflux and food intolerance after sleeve gastrectomy (SG). To date, there is no classification for gastric twist after SG. OBJECTIVE: This study aimed to propose an endoscopic classification for this condition and outline the clinical profile of these patients with sleeve gastrectomy. METHODS: Patients in the postoperative period of SG presenting endoscopic findings of gastric twist were included. All patients underwent an esophagogastroduodenoscopy 12 months after SG. The classification proposed consists of three degrees: degree I: mild rotation of the staple line without relevant shrinkage of the gastric lumen; degree II: moderate rotation of the staple line, leading to a focal area of fixed narrowing that requires additional maneuvers for its transposition; and degree III: severe rotation of the staple line leading to stenosis, with increased difficulty for transposition or complete blockage. RESULTS: Out of 2,723 patients who underwent SG, 45 (1.6%) presented gastric twist. Most patients were female (85%), with mean age of 39±10.4 years. In all, 41 (91.1%) presented degree I, 3 (6.7%) presented degree II, and 1 (2.2%) had degree III. Most patients were asymptomatic (n=26). Vomiting was the most prevalent symptom (15.5%). Statistically significant correlation of twisting degrees was not observed for both the presence of symptoms and the degrees of esophagitis. CONCLUSION: Gastric twist after SG is rare, with generally mild and asymptomatic presentation. The endoscopic classification was not statistically related to clinical presentation but set the ground for further analysis.

RESUMO - RACIONAL: A torção do tubo gástrico ou twist é uma das principais causas de refluxo persistente e intolerância alimentar após a gastrectomia vertical (GV). Até o momento, não há uma classificação proposta para a torção gástrica após GV. OBJETIVO: Propor uma classificação endoscópica para essa condição e descrever o perfil clínico desses pacientes. MÉTODOS: Pacientes no pós-operatório de GV apresentando achados endoscópicos de twist foram incluídos. Os pacientes foram submetidos a uma esofagogastroduodenoscopia 12 meses após a cirurgia. A classificação consiste em três graus. Grau I: rotação leve da linha de grampos, sem redução relevante do lúmen gástrico. Grau II: rotação moderada da linha de grampos, levando a uma área de estreitamento focal que requer manobras adicionais para a progressão do aparelho. Grau III: rotação severa da linha de grampos, levando à estenose, com grande dificuldade de progressão ou obstrução completa. RESULTADOS: Dos 2.723 pacientes que foram submetidos à GV, 45 (1,6%) apresentaram twist. A maioria dos pacientes era do sex feminino (85%), com idade média de 39±10.4 anos. Quarenta e um (91,1%) apresentaram twist grau I, 3 (6,7%) apresentaram twist grau II e apenas 1 (2,2%) apresentou twist grau III. A maioria dos pacientes eram assintomáticos (n=26). O sintoma mais prevalente foi vômito (15,5%). Não foi observada correlação estatisticamente significante entre o grau de twist e a presença de sintomas ou esofagite. CONCLUSÃO: Twist após GV é raro e geralmente assintomático. A classificação endoscópica proposta não foi estatisticamente relacionada com apresentação clínica, porém estabelece um referencial para análises futuras.

Hemorragia del tracto digestivo superior, enfoque para el médico general / Upper digestive tract bleeding, approach for the general Practitioner / Hemorragia do trato digestivo superior, enfoque para o médico geral

La hemorragia del tracto digestivo superior (HTDS) es el sangrado originado por encima del ángulo de Treitz. A pesar del aumento en las estrategias de prevención, del incremento en los tratamientos con Inhibidor de bomba de protones (IBP) y de la intervención endoscópica temprana, esta patología sigue siendo una causa frecuente de consulta a urgencias, con una morbimortalidad no despreciable y alta carga para el sistema de salud. Esta revisión se enfoca en la HTDS de causa diferente a las varices. La principal causante de esta entidad es la enfermedad ácido-péptica, que es consecuencia del gran consumo de antiinflamatorios no esteroideos (AINES) y de la infección por Helicobacter Pylori. Otras causas son el síndrome de Mallory Weiss, la esofagitis erosiva, las malformaciones arteriovenosas y la malignidad.

Upper gastrointestinal bleeding (UGIB) refers to any bleeding originating above the angle of Treitz. Despite an increase in prevention strategies, proton pump inhibitor (PPI) therapy and early endoscopic intervention, this pathology continues to be an important cause of admission to the emergency department for gastrointestinal causes, having a pretty high morbidity and mortality in addition to a high burden on the health system. This review focuses on non-variceal UGIB. The main cause of this entity being peptic acid disease, due to great consumption of NSAIDs and Helicobacter Pylori infection. Other causes are Mallory Weiss syndrome, erosive esophagitis, arteriovenous malformations, and malignancy.

A hemorragia do trato digestivo superior (HTDS) é o sangrado originado acima do ângulo de Treitz. Apesar do aumento nas estratégias de prevenção, do incremento nos tratamentos com Inibidor da bomba de prótons (IBP) e da intervenção endoscópica precoce, esta patologia segue sendo uma causa frequente de consulta a urgências, com uma morbimortalidade não depreciável e alta carga para o sistema de saúde. Esta revisão se enfoca na HTDS de causa diferente às varizes. A principal causante desta entidade é a doença ácido-péptica, que é consequência do grande consumo de anti-inflamatórios não esteróideos (AINES) e da infecção por HelicobacterPylori. Outras causas são a síndrome de Mallory Weiss, a esofagites erosiva, as malformações arteriovenosas e a malignidade. Palavras-chave: hemorragia gastrointestinal; úlcera péptica; endoscopia gastrointestinal; inibidores da bomba de prótons; medicina geral.

One- or two-operator techniques for oesophago-gastro-duodenoscopy in unsedated patients: A comparative prospective randomized study / Técnicas de uno o 2 operadores para la esofagogastroduodenoscopia en pacientes no sedados: un estudio comparativo prospectivo y aleatorio

Background: The standard oesophago-gastro-duodenoscopy procedure is performed with a single endoscopist (SE). Nurse-assisted (NA) oesophago-gastro-duodenoscopies have not yet been studied. We aimed to evaluate the efficacy of an NA endoscopy compared to an SE endoscopy.Methods: A prospective, single-center, randomized trial, in which 500 adult patients were divided into two groups. In the first group, patients underwent an endoscopy with an SE. In the second group, the endoscopy was performed with an NA. The ease of the procedure (scores 1–4; 1 difficult, 2 satisfactory, 3 easy, 4 veryeasy), evaluation of patient satisfaction (scores 1–4; 1 uncomfortable, 2 satisfactory, 3 comfortable, 4 verycomfortable), total time of the procedure and vocal cord observation were determined as quality indicators.Results: Mean patient satisfaction scores in groups 1 and 2 were 2.98±0.79 and 3.11±0.78, respectively (p=0.043), with uncomfortable ratings in 5.2% vs 4%, satisfactory in 16.8% vs 13.2%, comfortable in 53.2% vs 50.4%, and very comfortable in 24.8% vs 32.4% of patients in groups 1 and 2, respectively. Retching rates during the procedure were 54.4% and 45.2% (p=0.040) in groups 1 and 2, respectively. No differences were seen in vocal cord observation (54.4% vs 56.0%), total procedure time (2.35±1.56 vs 2.41±1.48min) and easy score (3.26±0.603 vs 3.25±0.64) in groups 1 and 2 for the procedures. Very easy, easy, satisfactory, and difficult ratings were given by 33.6% vs 34.8%, 60.4% vs 56.4%, 4.8% vs 7.6% and 1.2% vs 1.2% of groups 1 and 2, respectively.Conclusions: Compared with the conventional method, the assisted endoscopic technique provides more comfort and less gag reflex without increasing the processing time or difficulty of performing the procedure.

Antecedentes: El procedimiento estándar de esofagogastroduodenoscopia se realiza con un solo endoscopista (SE). La esofagogastroduodenoscopia realizada con una enfermera asistida (NA, por sus siglas en inglés) aún no se ha estudiado. Nuestro objetivo es evaluar la eficacia de una endoscopia asistida por una enfermera en comparación con un SE.Métodos: Se trata de un ensayo prospectivo, monocéntrico y aleatorizado. Quinientos pacientes adultos fueron divididos en 2 grupos. En el primer grupo, los pacientes se sometieron a una endoscopia con un SE; en el segundo grupo, la endoscopia se realizó con una NA. Se determinaron como indicadores de calidad la facilidad del procedimiento (puntuaciones 1-4; 1 difícil, 2 satisfactorio, 3 fácil y 4 muy fácil), la evaluación de la satisfacción del paciente (puntuaciones 1-4; 1 incómodo, 2 satisfactorio, 3 cómodo y 4 muy cómodo), el tiempo total del procedimiento y la observación de las cuerdas vocales.Resultados: Las puntuaciones medias de satisfacción del paciente en los grupos 1 y 2 fueron de 2,98±0,79 y 3,11±0,78, respectivamente (p=0,043), con puntuaciones de incómodo en el 5,2 frente al 4%, satisfactorio en el 16,8 frente al 13,2%, cómodo en el 53,2 frente al 50,4% y muy cómodo en el 24,8 frente al 32,4% de los pacientes de los grupos 1 y 2, respectivamente. Las tasas de arcadas durante el procedimiento fueron del 54,4 y el 45,2% (p=0,040) en los grupos 1 y 2, respectivamente. No se observaron diferencias en la observación de las cuerdas vocales (54,4 frente al 56,0%), el tiempo total del procedimiento (2,35±1,56 frente al 2,41 ±1,48min) y la puntuación de fácil (3,26 ±0,603 frente al 3,25 ±0,64) en los grupos 1 y 2 para los procedimientos. Muy fácil, fácil, satisfactorio y difícil fueron calificados por el 33,6 frente al 34,8%, el 60,4 frente al 56,4%, el 4,8 frente al 7,6% y el 1,2 frente al 1,2% de los grupos 1 y 2, respectivamente.

Caracterización clínica, endoscópica e histológica de la enfermedad inflamatoria intestinal

Introducción: La enfermedad inflamatoria intestinal es un padecimiento crónico de causa multifactorial, en los últimos años se ha incrementado el número de casos diagnosticados, por lo que su enfoque clínico-endoscópico e histopatológico es de vital importancia para proveer atención integral a los pacientes. Objetivo: Caracterizar clínica-endoscópica e histopatológicamente la enfermedad inflamatoria intestinal. Métodos: Se realizó un estudio observacional transversal, el universo estuvo constituido por 78 pacientes diagnosticados con enfermedad inflamatoria intestinal y la muestra quedó conformada por 54 pacientes. La información fue recogida en formulario a propósito de la investigación. Resultados: Predominaron los pacientes con edad de 50 años o más. Primó el sexo femenino y el color de la piel blanca. El síntoma cardinal más frecuente fue la diarrea y el tiempo de evolución que primó fue de cuatro a seis meses. La localización más frecuente de las lesiones fue el colon izquierdo y primó la colitis ulcerativa como principal variante. Predominó la mucosa de aspecto granular y las lesiones continuas en los rasgos endoscópicos, así como la distorsión de criptas y la inflamación de la lámina propia dentro de la histología. Sobresalió como principal complicación la fístula y de estos casos la mayoría requirió tratamiento quirúrgico. Conclusiones: Mayor afectación a pacientes de mediana edad, sexo femenino y de raza blanca. Principal síntoma asociado es la diarrea. Variante con mayor superioridad es la colitis ulcerativa. Adecuada correlación clínico-endoscópica e histopatológica. Las principales complicaciones encontradas fueron los trayectos fistulosos y la estenosis intestinal que requirieron en su mayoría tratamiento quirúrgico.

Introduction: Inflammatory bowel disease is a chronic disease of multifactorial etiology that in recent years has increased the number of diagnosed cases, so the clinical-endoscopic and histopathological approach is of vital importance to provide comprehensive care to patients. Objective: To characterize the inflammatory bowel disease clinical-endoscopic and histopathologically. Methods: A cross-sectional observational study was carried out. The universe was composed of 78 patients diagnosed with inflammatory bowel disease and the sample was made up of 54 patients. The data obtained from biopsy ballots were collected in a form. Results: Patients aged between 50 and 69 years old predominated. Female sex and white skin color prevailed. The cardinal symptom that predominated was diarrhea followed by enterorrhagia and the time of evolution that prevailed was 4 to 6 months. The most frequent location of the lesions was the left colon and ulcerative colitis predominated as the main variant. Continuous lesions and granular appearance of the mucosa predominated in endoscopic features, while in histological features crypt distortion and inflammatory infiltrate of the same layer prevailed. Among the complications, the fistula stood out and most of these patients required surgical treatment. Conclusions: Greater affectation in middle ages, female and white skin color patients. The main associated symptom is diarrhea. The most common variant was ulcerative colitis. Adequate clinical-endoscopic and histopathological correlation was evidenced. The main complication was the fistulous tracts and intestinal stenosis, that mostly require surgical treatment.
